Reflection: Shared Expectations What Were They Thinking?! - Section 3: Number Talk


 Many of my students just wait to be told what to do and how to do it so they can practice the prescribed method without taking the time to understand it. But when we do Number Talks with mental math my students are generating the number properties of addition themselves, describing the patterns and relationships, and explaining not only why it works, but why it helps. It helps them connect to their own intuition about math and pay attention to the relationships between numbers and the flexibility in operations. I think Number Talks is one of the most effective ways of elicit multiple methods and to get students to articulate their reasoning. It gives validation to all strategies and allows students to work at their level of comprehension. I found that students who had already seemingly given up on their math abilities were inspired by Number Talks to reengage.

Lesson 8 of 9

Objective: SWBAT describe the various mental math strategies demonstrated by classmates and begin to understand the properties behind them.

Big Idea: Students will start to generalize a variety of strategies to uncover the number properties of addition.
